ELECTRICAL CONDENSER Filed Jan. 16, 1930 T 9 if 2 11mm @HMJKDFP Patented Apr. 21, 1931 UNITED STATES PATENT OFFICE FARNUM F. DORSEY, OF ROCHESTER, NEW YORK, ASSIGNOE TO NORTH EAST APPLIANCE CORPORATION, OF ROCHESTER, NEW YORK, A CORPORATION OF NEW YORK ELECTRICAL CONDENSER Application filed January 16, 1930. Serial No. 421,163.

This invention relates to condenser assemblies of the type in which a condenser having the form of a-roll of paper and metal foil is inclosed within a tubular metal housing, which is closed at one end by means of a disc of insulating material.

The object of the invention is to provide, in such' an assembly, a simple and efiective construction involving the disc or head which closes the housing, the binding post or terminal, and the means for connecting the terminal with the foil of the condenser.

To the foregoing end, the invention consists in the construction hereinafter described, and illustrated in the accompanying drawing, as it is defined in the annexed claims.

In the drawings Fig. 1 is a partly sectional side elevation of a condenser assembly embodying the present invention. Fig. 2

assembled.

is a section on the line 2-2 in Fig 1, looking from left to right, and Fig. 3 1s a plan view of the terminal as it appears prior to the operation by which the parts are The invention is illustrated as'embodied in a condenser assembly of the type used in electric ignition apparatus, and is shown on an enlarged scale. The condenser 5 may be of the usual form, comprising a cylindrical roll of strips of paper and foil, with the edges of the foil exposed at each end to facilitate the making of connections therewith. This condenser is enclosed within a drawn tubular housing 6, of which one end is closed by a disc 7 punched from sheet insulating material such, for example, as micarta. The binding post characteristic of the present invention is of U shape. Its middle member 8 has a threaded perforation 9 to receive a binding screw, while its two parallel legs have portions 10 of reduced width, which pass through perforations 1n the disc 7, while the wider parts ofthe legs provide shoulders 11 to rest against the outer surface of the disc.

A connector 12 rests against the inner surface of the disc, this connector being made of sheet metal and provided with a serrated marginal flange 13, adapted to embed itself in the foil projecting at the end of the corn denser. The reduced ends 10 of the terminal in the end of the housing and the edge of the latter is then spun over, as shown in Fig. 1, to lock the head in place. In the course of the operations just described the necessary connections are made with the condenser without any attention on the part of the manufacturer.

The particular form of the connectors shown in the drawings, and the other details of construction which are not particularly described, are not intended to be set forth as parts of the present invention, the features are novel and patentable in this application being set forth in the following claims.

I claim:

1. A condenser assembly comprising: a condenser of the rolled type, a metal housing enclosing the condenser, an end closure for the housing consisting of a plate of insulating material secured, at its edges, to the housing, a sheet-metal connector lying agalnst the inner surface of said end closure and provided with integral projections engaging the end of the condenser, and a termlnal member of sheet metal bent to U shape and having two legs extending through the end closure and the connector and riveted against the connector, said legs having shoulders engaging the outer surface of the end closure.

2. A condenser assembly comprising: a condenser of the rolled type, a housing enclosing the condenser, an end closure for the housing including a plate of insulating material secured at its edges to the housing, a connector lying against the inner surface-of said end closure and provided With means engaging the condenser, and a terminal member of arched form having legs extending through the end closure and the connector, said terminal member being electrically secured to the connector, zind the legs thereof having shoulders engaging the end closure.

In testimony whereof I hereto aflix my signature.
